    Thank you very much Richard. Definitely looks like the Emilar horn.

    Are these considered inferior to the original Altec designs?

    If you intend to run the speakers with a single amp I would look at changing amplifiers. You run a near $20k AUD DAC with a cheapish Chinese Integrated tube amp. Plenty of high power SS Integrated...

    The switch is definitely worth bypassing. I personally wouldn't bother with the capacitors, if I were spending money I would build charge coupled networks and call it a day. IME you benefit just as...

    JBL 4430's - Do they lack mid-bass???

    Bought a pair of 4430's awhile back but they ended up in storage so I never really got to play them. With my 4350's getting the cabinets redone the 4430's are now front and centre in my room.

    I would say the original KSA50/KSA100 are certainly forgiving and somewhat dark sounding. I don't think the highs will get jagged, will see.

  7. Could a Krell KSA50 run a pair of L250's?

    Title says its all. Is a ultra high current 50 watt amp enough for the L250's?

    From Stereophile:

    The Krell KSA-50 is new-wave enough, however, to be an incredibly stiff class-A design, rather...

    You need to find out the value of the components on the cards. Those values will correspond to a frequency and slope within the user manual.

    I use a MiniDsp UMIK and REW. The mic comes with a calibration file specific to it. I think the consistency of my sweeps is an indicator they are somewhat useful.

    Going through old posts I can see a few members mention balancing the HF and LF sections by measuring with an SPL meter.

    Can someone please detail what the process is?
